SHUTTER-WORKER.

SPECIFICATION forming part of Letters Patent No. 360,708, dated April 5, 185.7.

Application filed December 20, 1886. Serial No. 222,041. (No modell To all whom it may concern.-

Beit known that I, FRANK B. ll/IALLORY, a citizen of the United States, residing at Flemington, in the county of McDonough and State of New Jersey, have invented certain new and useful Improvements in Means for Hanging and WVorking \Vindow Shutters; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention consists in certain novel constructions and combinations of parts, as hereinafter described and specifically claimed, whereby shutters can be underhung upon pendent pintles and sustained by a support applied directly to either the upper or lower hinge-pintle, instead of to the window-frame or wall of the building, and such support so constructed that it can be utilized for keeping the thread of the wornrshaft and the teeth of the worm-wheel in positive contact, and thereby prevent rattling sounds from slight vibra iions of the shutter.

In the accompanying drawings, Figure l is intended to represent a vertical section through either a window frame, casing, or wall of a building and the hinge-bracket housing of a well-known shutter-worker on the line of the worm-shaft of such shutter-worker, the shutter being closed, and the bracket of the shutter-hinge leaf attached to it, and the ice or snow scraper at the bottom of the shutter being shown in elevation. Fig. 2 is a vertical section of the hingebracket housing in the line of the shaft of the worm-wheel, the window frame or easing or wall of the building, the shutter, the hinge leaves and pintles, brackets, and shutter-support of the upper hinge and the lower bracket of the lower hinge being shown in elevation. Fig. 3 is a detail view of the upperhinge, with apin and plate support substituted for the spring keypin shown in Figs. 1 and 2. Figs. at, 5, 6, 7, 8 illustrate different constructions of supports for shutters underhung on pendent pintles, such supports being applied tothe lower shutter-hinge pintles. Fig. 9 is a view of a modified form of lower hinge-leaf, the same being cast with an opensided square passage for a lower square pintle-extension of the wormshaft to enter in hanging the shutter. Fig. 10 is a view of the lower hinge-leaf which is attached to the shutter, illustrating that it may be fastened to the shutter by bolts and nuts, instead of wood-screws; and Fig. 11 is an elevation of the upper hinge, showingits support for a shutter, and the eye-bracket of the hinge leaf attached to the shutter, constructed with an inclined surface for preventing the shutter vibrating and the thread of the worm and the teeth of the worm-wheel of theshutter-worker from being moved apart by a slight force of the wind upon the shutter.

A in the drawings, Figs. 1 and 2, is intended to represent either a portion of a window frame, casing, or wall of a building, and B the shaft of a shutter-worker passed through said frame or wall, and having a crank-handle, a, on its inner end and a worm, O, on its outer end.

D is a two-part housing, constructed similar to the housing for the same purpose shown and described in my application for a patent for a means for hanging and working shutters, filed in the United States Patent Oiiice on the 15th day of December, 1886, and which is not claimed inthis patent further than it is an element in combination with certain parts not shown in said application.

E is the ordinary worm-wheel shaft, carrying worm-wheel E, and suspended by means of a collar, 1), from the inside of the housing, and having a straight flat-sided vertical pendent revolving pintleextension, E, which passes through the bottom plate of the hinge-bracket housing and enters the square eye of the bracket (1 of the hinge-leaf-F, attached to the shutter F, as shown. The upper hinge comprises two leaves, G G, one having a stationary pendent round pintle, c, on itsbracket (l, and the other a round eye in its bracket f. The shutter F is underhung upon the lower pintle, Ff, and upper pintle, c, and beneath the bracket (2 a collar, H, is slipped upon the upper pendent pintle, c, and a spring key-pin,I, passed through holes in the collar and pintle, as illustrated in the figures named The shutter is supported on the collar H, and by turning the worm-shaft from the inside of the room by its crank-had dle the shutter can be opened and closed on its pintles, and held open or closed, as desired.

KOO

In Fig. 3 I have shown an uppersupporting cross-bar, I, secured by means of a re1nova ble pin, in a horizontal slot formed in the pintle c.

In Figs. 4 and 5 I have shown ashutter-supporting device, I", applied to the lower hingepintle, E instead of to the pint-1e c, said device being a nut or nuts screwed upon a cylindrical threaded end portion below the square portion of the pintle E as shown.

In Figs. 6 and 7 I have shown a shutter-support, 1 similar to the one shown in Figs. 4 and 5; but instead of making the pintle E with a square portion to fit the eye of the bracket of the hinge-leaf attached to the shutter, I have formed the eye-bracket of said leaf with angular teeth It and provided the pintle with a round integral collar, it, having teeth similar to those 71. By this construction the shutter hinge-leaf can be made rigid with the pintle E the same as if the pintle and the eye of said hinge-leaf were made square.

In Fig. 8 I have shown a simple setscrew, I screwed into the eye-bracket d of the hinge-leaf attached to the shutter, and made to bind against or enter a socket in the square portion of the pintle E, and thereby serve as a support for the underhung shutter. I do not regard this as avery substantial construction, and prefer the other plans shown.

In Fig. 9 I have shown thehinge-leaf, which is attached to the shutter, cast with separated brackets with open slots, 2', and by this construction the hingeleaf can be cast without a core, which saves expense of manufacture.

In Fig. 10 I have shown that bolts and nuts m m may be used instead of wood-screws for fastening the hinge-leaf to the shutter, and in Fig. 11 I have shown the supportingcollar H. for use on the pintle of an upper hinge, and constructed with an inclined surface, a, while the bracket of the hinge-leaf attached to the shutter is formed with reversely-inclined surface, a. By this construction the weight of the shutter, in connection with the resisting inclined surfaces at it, prevents rattling of the worm and worm-wheel gearing, as slight winds are not liable to move the shutter up the inclined surface, so as to cause the thread of the worm and the teeth of the worm-wheel to separate and vibrate against each other.

I am aware of the gate-hinge of WVhiting, patent numbered 152,714, and make no-clai1n for anything therein shown.

My invention enables me to suspend the shutter upon under-hanging supports applied on the pendent pintles of the hinges; and the form of these supports can be such as will insure the weight of the shutter resting bodily upon the supports, and thereby the tendency of the shutter to slightly swing back and forth overcome.

What I claim is l. The combination, with the upper stationary pendent pintle and lower pendent turning pintle of shutter-hinges, of the shutter-support applied to a pintle of said hinges and in bearing relation to the said pintle, and the eye-bracket of the hinge-leaf attached to the shutter, substantially as and for the purpose described.

2. The combination, with the shutter-working gearing described, and with the upper stationary pendent pintle and lower turning pendent pintle of shutter-hinges, of the shut ter-support formed with an inclined surface, a, and applied below the eyc'bracket of a hingeleaf which is attached to a shutter and formed with an inclined surface, a, substantially as and for the purpose described.

In testimony whereof I affix my signature in presence of two witnesses.
